“That was one hell of a run,” Morgan said to the Supernatural family. “I hope this last year is enough time to wrap up a story that deserves only the best.” Morgan then included a special message to Ackles and Padalecki, his TV sons, saying, “ya done us proud.”

One more twit for the day, it’s late. I just want to say to all of @cw_spn family… that was one hell of a run. I hope this last year is enough time to wrap up a story that deserves only the best. My love to cast, crew and fans. @JensenAckles and @jarpad ya done us proud Xojd

At this point, we don’t know anything about the final season, but Morgan previously told EW that he’d love to return before the show says goodbye. “My dream would be to come back and do something in the last year, the last episode, the last couple episodes, whatever, and do a proper little arc,” he said. “It’d be fun to have some time and really dig in,” he says, adding, “Maybe [episode 300] won’t be the end of John. Like I always say to everybody: ‘It’s Supernatural, anything can happen.’”
